PUMP.'

SPECIFICATION forming part of Letters Patent No. 237,240, dated February1, 1881.

Y Application filed November 2,1880. (No model.)

To all @L1/wm it may concern Be it known that I, BENJAMIN BRANsoN, acitizen ofthe United States, residing in Philadelphia, Pennsylvania,have invented Vcertain Improvements in VVVell-Pumps, of which thefollowing is a specification.

My invention relates to the construct-ion of well-pumps in whichwrought-iron tubular rods constitute part of' the frame; and the objectof my invention is to construct a substantial, light, and economicalpump ot' this character, and to combine therewith a vacuum-chambercheaply constructed in the manner explained hereinafter.

In the accompanying drawings, Figure l is a vertical section ot' myimproved pump; Fig. 2, a sectional plan on the line l 2; Fig. 3, asectional plan on the line 3 et; Fig. 4, a sectional plan on the line 56, and Figs. 5 and 6 views illustrating modifications of my invention.

The portion A ot' the pump, which is generally above ground, and whichis termed the stock, consists of the plate a, secured to a suitablefoundation, four wrought-iron tubes, b, b', b2, and b3, and the topplates, c, carrying the bracket e, to which the handle B is pivoted.These rods may be screwed into the foundation-plate a and into the upperplate, c,- but I prefer to screw the two rods b b(shown in Fig. l) tothe base-plate, and let them pass freely through the upper plate, abovewhich they are furnished with nuts, the other tubes, b2 and b3, simplyfitting into sockets in the upper and lower plates, and being securedtherein by tightening the nuts of the rods b b. By this mode ofconstruction a light, and at the same time substantial, stock isobtained.

The main pump-barrel D is suspended within the well by means ot' twotubular rods, dd', the Aattachment of these rods to the plate aandpump-barrel being made in any manner which may be deemed most convenientand economical, but so that the rod d. shall communicate with the rod11,'the two rods constituting the force-pipe, having its outlet at thespout h. The two rods d and b may also communicate with each other, butthis is not absolutely essential.

It may be remarked here that the tubular vthe pump-barrel; or the rodmay have any vother direct communication with the suctionpipe below t-hesuction-valve m.

It is well known to those familiar with pumps that a chambercommunicating with a suction-pipe, but otherwise closed, contributes tothe easy working ot' the pump; hence such chambers are frequentlyapplied'A to rapidlyworking steam-pumps, andare termed vacuum chambers!!In my improvements this chamber is economically formed, partly by thetube d and partly by the passage t' i forming the communication betweenthe said tube and the suction-pipe; and if a chamber of large capacityis desired, the interior ot' the tubular rod b' may form an extension ofthe vacuumchamber,

The suction or foot valve 'm may be of the ordinary construction, asalso may be the bucket or piston a, which, in the present instance, isconnected to a tubular pump-rod, G, theinterior of which constitutes theair-chamber, and the upper end of which is ljoined to the short arm ofthe pump-handle B. n A supplementary barrel, H, projects above vandcommunicates with the main barrel, and

to this supplementary barrel is adapted a piston secured to the tubularpump-rod. It should be understood, however, that neither the valve,buckets, supplementary barrel, nor tubular pump-rod, serving as anair-chamber, constitute any part of my present invention.

A substantial pump-stock may consist of three tubular rods, arranged asshown in Fig. 6,-one of these rods serving as the dischargepipe, and oneof the other rods serving as part Vof the vacuum-chamber.

`plate,o, having a bearin g for the pump-handle,

IOO

are combined with tubular Wrought-iron rods, forming,vwith said plates aand c, the stock of the pump, all substantially as set forth.

2. A pump in which a barrel, D, and plates aand 0 are combined withtubular Wroughtiron rods, which serve to connect the said barrel andplates together, substantially as described.

3. The combination of the base-plate a, the top plate, c, the rods b2b3, adapted to sockets in said plates, and the rods b and b', serving toclamp the plates ci and 0 together and ooniine the rods b2 and Z13, therod b forming an extension of the discharge-pipe of the pump, allsubstantially as set forth.

4. The combination of the base-plate ct, the pump-barrel D, andsuction-pipe E with va tubular supporting-rod forming a vacuumA chamber,or part thereof, communicatingwithl the suction-pipe below thesuction-valve m, all zo substantially as set forth.

5. The combination of the suction-pipe E of the pump, the pump-barrel D,having an extension inclosing a passage, z', and the coupling x, havinga passage, i', leading from the 2 5 passage i to the suction-pipe, asset forth.

In testimony whereof I have signed myname to this specification in thepresence of two subscribing witnesses.

BENJAMIN BRANSON.
